1 Claim.

This invention relates to a gauge, the general object of the inventionbeing to provide a gauge for facilitating the setting of anchor pins ofhydraulic brakes when relining brake shoes.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote likeor'corresponding parts throughout the several views, and in which:-

Figure 1 is a view of a hydraulic brake, showing the gauge in use.

Figure 2 is a plan view of the gauge.

Figure 3 is a perspective view of the gauge, with parts broken away.

As shown in these views, the numerals 1 and 2 indicate a pair ofsubstantially L-shaped members formed with a shank 1' and a head 1",each head having a notch 3 therein. Each shank is formed with a threadedhole for receiving a screw 4 which passes through the slot of a plate 5which rests on the shanks and a washer 6 is placed between the head ofeach screw and the plate.

The notches are shaped to fit the pins 7 which pivotally connect thebrake shoes A to the drum B, as shown in Figure 1. As is understood, thepins 7 must be replaced, when removed from the brake assembly in thesame position that they originally occupied and this device facilitatesthe placing of the pins in their original position.

In using the device and before the brakes are removed, the members 1 and2 are placed over the pins 7, as shown in Figure 1, after the screws 4are loosened and after the members are placed over the pins, the screwsare tightened to hold the parts in adjusted position. The device is thenremoved from the pins and set to one side and then the pins are removedso that the brake shoes may be removed and relined or repaired. When thebrakes are put back in position, the anchor pins are put back in place,but their lock nuts are left loose so that the pins can be adjusted tofit the gauge, it, of course, being understood that the gauge is pickedup and placed over the pins after they are adjusted to fit the gauge.When the pins are so adjusted, the lock nuts are tightened and then thegauge can be removed. Thus the device will enable the pins to be placedin the exact position they occupied before they were removed.

In order to facilitate the placing of the gauge on the pins, one of themembers provided with the notches should be marked with the numeral 1and the other with the numeral 2 and the pins 7 should also be markedwith the numerals 1 and 2 so that the member marked 1' can be readilyplaced on the pin marked .1 and the member marked 2 on the pin marked 2.

This gauge eliminates guess work for the mechanic and also saves time.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that-changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claim.

What I claim is:-

A gauge of the class described comprising a pair of members, each havinga shank and a head, said head extending from one side of an end of theshank, each head having a notch therein which extends at right angles tothe length of the shank and opens out through the free side edge of thehead, an elongated plate having one face contacting and overlapping thetwo shanks and having an elongated longitudinally extending slottherein, the ends of which extend over the shanks, and screws passingthrough the slot and threaded into the shanks for slidably and rotatablyconnecting the shanks to the plate and for holding the pair of membersin the position to which they have been adjusted when the screws areloosened.
